My highstock will not open data in a chart on localhost. Does anybody has any idea why?
The chart displays no date. I have tried localhost, ipaddress, and still no luck.

$password="";
$db_name="northwind";
$con=mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$sql = "select unix_timestamp(OrderDate) as datetime, Freight from TEST1 ORDER BY OrderDate ASC LIMIT 100";
$result = mysql_query($sql);
$data = array();
while ($row = mysql_fetch_array($result)) {
extract ($row);
$datetime *= 10000; // convert from Unix timestamp to JavaScript time
$data[] = array((float)$datetime,(float) $Freight);
}
$array2[] = json_encode($data);
///data2[] = json_decode($array2);
echo json_encode($data);
?>

Everything seems to be working fine with your code.
Demo
In your $.getJSON(...) you need to take care of the Same Origin Policy
You have not specified what errors you get or what problem are you facing, it is really difficult to help in such cases. Please consider posting a jsFiddle reproduction of the error
Ok, used the northwind database on PHPmyadmin with WAMP, on localhost, it is working. Forgive the sloppiness, it's late. If you have issues, please let me know.

$result = mysql_query($sql);
if($result === FALSE) {
die(mysql_error()); // TODO: better error handling
echo mysql_error();
}
$data = array();

I am trying to add accessibility to an donut chart created using Highcharts.
Html code:

});
The JSFiddle.
When I use NVDA with Firefox(version 83) on Windows 7, the screen reader doesn't read the description specified in the HTML as specified in the documentation(https://www.highcharts.com/docs/accessibility/accessibility-module). Same is the case for JAWS on IE.
In fact,my data is weekly data.
This data is from the 1st week to the fiftieth week in 2015 year.
data: [
1884,2936,2039,1948,1814,2071,2183,3234,3426,2188
,1884,2936,2039,1948,1814,2071,2183,3234,3426,2188

,1884,2936,2039,1948,1814,2071,2183,3234,3426,2188
]
I want to show the first week to fiftieth weeks in 2015 on the X axis，but how to modify my code?
I do not find the year-week format data for "pointStart",and how to set "pointInterval" value is weekly?

I wonder if anyone can tell me what is wrong in my code please? I want to be able to select a polygon and show a graph in a popup using leaflet and highchart. I have managed to create the graph in the popup, but the line is missing on it, and I also get a separate div showing the same chart (and the line) at the bottom of my web page which I don't want. Can anyone tell me how to get the line to show on the chart in the popup and to remove the separate chart? Here is my code.enter code here

You don't need the div element in your HTML markup. You can create one on the fly in your onEachFeature function and add it to the popup. Also, you need to initialize your highchart after the popup has opened, not before. In code with comments:
new L.GeoJSON(feature, {
onEachFeature: function (feature, layer) {
// Create div with class name highchart
var div = L.DomUtil.create('div', 'highchart');
// Bind popup to layer with div as content
layer.bindPopup(div);
// Handle event when popup opens
layer.on('popupopen', function (e) {
console.log(e.target); // layer object
console.log(e.target.feature); // layer's feature object
console.log(e.popup); // popup object
console.log(e.popup.getContent()); // the div
// Now do the highcharts stuff
Highcharts.chart(e.popup.getContent(), { /**/ });
});
}
});
And don't forget to set the div's dimensions with CSS:
.highchart {
width: 500px;
height: 200px;
}
Previous help here has got me to the current stage with my Highcharts project, however I am still hitting a major stumbling block. Highcharts chart is not loading data retrieved using .getJSON. I am at a loss as to why the html is not rendering the chart and load the data from data.php. All code below, does anyone have any ideas? #PawełFus
php
<?php
$con = mysql_connect("ip_address","root","");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("test", $con);
$result = array();
$sql = mysql_query("SELECT unix_timestamp(DATETIMES), TEST FROM PR");
$result['name'] = 'TEST';
while($r = mysql_fetch_array($sql)) {
$datetime = $r[0]*1000;
$result['category'][] = $datetime;
$result['data'][] = round($r[1],2) ;
}
$json = array();
array_push($json,$result);
print json_encode($json);
?>
php return

Your series array (in options) has no object, so you cannot use series[0].name. Secondly your json is not used correct, but try to replace this lines:
options.xAxis.categories = json['category'];
options.series[0].name = json['name'];
options.series[0].data = json['data'];
with
options.xAxis.categories = json[0]['category'];
options.series[0] = {};
options.series[0].name = json[0]['name'];
options.series[0].data = json[0]['data'];
my json.data file is in the same directory as my index.html file. data.json file looks like this:
{
data:
[
[1369540800000,20]
]
}
when I do:
alert(JSON.stringify(jsonData, null, 4));
I get this back, so I get the values. Still dont know what is wrong.
{
"data":[
[
1369540800000,
10
],
[
1369541700000,

Your data is not in the right format. Familiarize yourself with how to format data for Highcharts.
These may help:
http://api.highcharts.com/highcharts#series.data
http://docs.highcharts.com/#preprocesssing-data-from-a-file
Notably:
1) your dates must be either a javascript time stamp (epoch time, in milliseconds), or a date.Utc declaration
2) your structure needs to be like:
[[date, value],[date,value],[date,value]]
this is what I had to do to make it work:
<script src="js/highcharts.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container',
type: 'area'
},
xAxis: {
type: 'datetime'
},
series: [{}]
};
$.getJSON('dude.json', function(data) {
options.series[0].data = data;
